Arduino网络套接字自动连接

Question

我使用的是2个esp8266，它们都连接到同一个网络。Esp1使用websocket向esp2发送一些数据。所以基本上esp2连接到esp1的websocket并读取数据。我的问题是，如果esp1重新启动，在再次启动后，esp2将不再连接到它，需要重新启动才能连接这是我在esp2 上使用的代码

#include <ESP8266WiFi.h>
#include <WebSocketsClient.h>
#include <ESP8266WebServer.h>
#include <SoftwareSerial.h>
#define USE_SERIAL Serial
#define LEDS 0 //Status led
WebSocketsClient webSocket;
SoftwareSerial COM(5, 4); 
long previousMillis = 0;
long interval = 50;
String data;
void webSocketEvent(WStype_t type, uint8_t * payload, size_t length) {
switch(type) {
case WStype_DISCONNECTED:
yield();
break;
case WStype_CONNECTED: {
webSocket.sendTXT("Connected");
}
yield();
break;
case WStype_TEXT:
if(payload[0] == '#') {
uint32_t dataz = (uint32_t) strtol((const char *) &payload[1], NULL, 10);
if (dataz < 99911) {
data = "0" + String(dataz);
}
else {
data = String(dataz);
}
}
yield();
if (data.length() == 6 ) {
COM.print('<'); // start marker
COM.print(data);
COM.println('>'); // end marker
}
break;
}
}
void setup() {
pinMode(LEDS, OUTPUT);
digitalWrite(LEDS, LOW);
for(uint8_t t = 4; t > 0; t--) {
delay(1000);
}
WiFi.mode(WIFI_STA);
WiFi.begin("xxx", "xxx");
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
}
// server address, port and URL
webSocket.begin("192.168.0.30", 81, "/");
// event handler
webSocket.onEvent(webSocketEvent);
// use HTTP Basic Authorization this is optional remove if not needed
//webSocket.setAuthorization("user", "Password");
// try ever 5000 again if connection has failed
webSocket.setReconnectInterval(5000);
digitalWrite(LEDS, HIGH);
}
void loop() {
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval) {
previousMillis = currentMillis;
webSocket.loop();
}
}

当esp1在断开连接后再次可用时，我需要一些帮助来重新连接非常感谢

webSocket.loop((；应在if语句之外。
